Stainless steel Big Boat couplers join two traveler cars, by attaching through the shackles on each car, to form high-load assemblies. The 580 coupler fits the shorter T3201B traveler cars. It is too short to join the longer, high load T3201B.HL cars.
Use 752 couplers for single-point mainsheet attachments using Black Magic single, double or triple mainsheet blocks.
Maximum working load is 9,000 lb.
